Default Dendrobium chrysanthum with round black spots -- is it a virus?

This is my Den. chrysanthum purchased from a nursery about two months ago. Recently I've noticed black ring-like spots developing on some of the leaves. And there are some light-colored patches on newly emerged leaves too.

Are these signs of viral infection? Shoud I destroy this plant?
